Overview:
This research seeks to quantify the flow volume of rainfall-derived inflow (RDI) from residential foundation drains (also known as weeping tile). The results suggest that the RDI from residential foundation drains can contribute up to 85% of the total volume in sanitary sewers should they be connected. Disconnecting residential foundation drains can significantly reduce the flow volume in the sanitary sewer by 78%. Research also developed guidance for authorities for how to collect data efficiently in the future for basement flooding projects. Results indicated that a minimum of 39 storm events data are needed to be collected in order to produce a statistically sound estimation of RDI. This research also investigated the merit of using lot-level modelling techniques in stormwater management models in order to compare the efficiency of low impact development at residential lot-levels. This research evaluates the benefit of installing LID on residential properties to reduce surface runoff during storm events and considers the effect of climate change on increased large rainfall events and LID performance to reduce surface runoff.
